Institut auf dem Rosenberg

Institut auf dem Rosenberg is a private international boarding school located near Lake Constance in St. Gallen, Switzerland. Founded in 1889, it is one of the oldest boarding schools in Switzerland and reportedly the most expensive school in the world. As of 2025, it has a tight-knit student body of around 280 students drawn from 60 nationalities. It has educated diplomats, oligarchs, world leaders, Nobel laureates, and generations of global aristocracy and industrial dynasties, and has been referred to as the "davos" for children".

The school has 28 co-curricular facilities attached to its 13 art nouveau residences. The student-built SAGA Habitat and ETH Zurich greenhouse allows for the study of various engineering and agricultural cybernetic disciplines. The main campus, 25-hectares on the edge of Lake Constance, with adjoining school villas immediately across, feature "wind-trees" co-designed by Rosenberg students to generate renewable energy. The HumaniX Pavilion offers computer science and mechatronics capacity-buildings programs for students as young as 6, and the private parklands nearby include ten sports pitches, two shooting and hunting ranges, and five in-house theatres. Rosenberg also owns a private alpine club offering 12 local sports, a polo school, and a riding arena.

Rosenberg was named the world's Best Boarding School in 2024 by Premium Switzerland. It is included in The Schools Index of the world's 150 best private schools and among top 10 international schools in Switzerland. It accepts no external funding or donations.

The Swiss educational reformer Johann Heinrich Pestalozzi inspired the philosophy of the school and one of his quotes, "to learn, to live is the goal of all education," is Rosenberg's official motto.
